Request InfoInternational Crystal LaboratoriesPolystyrene calibration films for FTIR spectrophotometers are available from International Crystal Laboratories. They come with a 38-µm pathlength or in sets of two pathlengths for more precise calibration. Traceable to NIST 1921, the films come freestanding or, to prevent fringing, deposited on KBr windows either undoped or doped with boron. They are radially symmetric, eliminating orientation effects of extruded films.See full productRelated content from Photonics MediaWEBINARSPhotonics.com 7/22/2021STANDARDS UPDATE: Vision Standards: An Overview of Global and A3 DevelopmentsStandards play a key role in the vision and imaging industry by ensuring interoperability of components, increasing market size, and shortening the time it takes to get new products to market.
